HAIR-PIN.

Specification of Letters Patent.

Application filed November 23, 1915. Serial No. 63,122.

To all whom it may concern;

Be it known that I, MARTA KALINOWSKA,

a subject'of the Czar of Russia, residiiig at New York, in the countyandState of New York, have invented certain new and useful Improvements inHair-Pins, of which the following is a full, clear, and exactspecification.

This invention relates to hair pins, and has for its object to providean improved hair pin of the type having pivoted prongs adapted to grippart of the hair placed between them for preventing the device frombeing jarred out, as is so apt to occur in dancing or active exercise. I

It is the aim of this invention to produce a'hair pin of this type whichwill effectively hold itself in the hair, but which has the appearance,when in place, of an ordinary hair pin having rigid prongs.

Another object is to so construct the hair pin that the handle oroperating end of the movable prong will not be. apt to be accidentallydisplaced-and the device thus re- I leased from the hair.

Other objects will appear as the description proceeds.

The invention will be first hereinafter described in connection with theaccompanying drawings which constitute part of this specification, andthen more specifically defined in the claims at the end of thedescription.

In the accompanying drawings, wherein similar reference characters areused to designate corresponding parts throughout the several views:Figure 1 is front elevation of a hair pin made substantially inaccordance with this invention, a part of the fixed prong being brokenaway to disclose the rubber strip carried by the movable prong, andtheopen position of the movable prong being indicated in dotted lines.Fig. 2 is a longitudinal section through the prongs of the hair pin,taken from side to side, the

head being broken away, and Fig. 3 is a" cross section throligh theclosed prongs of the device. 1

The hair pin, as illustrated, comprises a fixed prong 1 and a movableprong 2 pivoted together at 3. The fixed prong is so called because itis permanently attached to the ornamental head 6 by the arm 4, whereasthe movable prong has a diverging arm 5 which is movable with respect tothe head 6, although said arm 5 is purposely made to closely resemblethe arm 4 of the fixed prong and extends into uxtaposition to the head6, as indicated at 7.

Both prongs are made in channel form,

the prong 2 being of less thickness so that it may 'fold into thechannel of the fixed prong 1, as shown best in Fig. 3. The channel inthe prong 2 is fitted with a filling strip 8, preferably of rubber,which provides an effective gripping surface within the channel of thefixed prong 1.

The'prongs are yieldingly held together 1n folded or gripping position,as shown in solid lines in Fig. 1, by a spring 9 housed in the channelsin the arms 4 and 5. This the channel of the arm 5 and bears uponthebase of said channel for holding the prongs closed,.as will be readilyunderstood. When it" is desired to open or spread the prongs apart, aswhen the hair pin is to be placed in the hair, it is only necessary topress upon the arm 5 of the movableprong and moveit toward the arm 4 ofthe fixed prong, whereupon the prong2 will be swung away from the prong1, as indicated in dotted lines in Figs. 1 and 2. After the prongs havebeen inserted into the hair in open position, the pressure is removedfrom the arm 5 and the spring 9 immediately closes the prong 2 upon theprong 1, firmly gripping the hair between them. The channel form of theprongs makes them very strong and rigid, \while the rubber strip used inthe channel of the movable prong provides a good and tenacious grip onthe hair. The arrangement of the end 7 of the arm 5 of the movable prongin juxtaposition to the head, while the latter overhangs and is arrangedin the same plane with said arm,

makes it almost impossible to accidentally Patented Aug-[15, 1916.

verging arms on the other side of the pivot,

and a head secured to the arm of one prong and extending across and intojuxtaposition to the arm of the other prong and in the plane thereof,for the purpose specified 3. A hair pin comprising a pair of prongspivotally connected together, both prongs having channels facing oneanother, one channel being narrower than the other and adapted to foldinto the same and a strip of rubber secured in the narrower channel forthe purpose specified. I

4. A hair pin comprising a pair of prongs pivotally connected together,one prong havside of the pivot, and a spring for yieldingly holding theprongs in closed position, said spring being entirely housed in thechannels in said arms;

In testimony whereof I have signed my name to this specification.
